Abstract A novel control strategy for single‐phase unidirectional switching‐mode rectifier (SMR) that draws a sinusoidal line current in phase with the supply voltage is proposed and discussed in this paper. In the adopted circuit topology, two AC power switches are placed between the AC side of the SMR and the center‐tapped terminal of the DC‐link capacitors. The control schemes are based on the hysteresis current control (HCC) technique and the simple look‐up table. The control schemes, stored in a programmable array logic (PAL), are implemented such that the line current is driven to follow the current command. There are three voltage levels (u DC , u DC /2, 0) on the AC side of the rectifier in each half cycle. The blocking voltage of each AC power switch is clamping to half of the DC‐link voltage. Software simulations and experimental circuits are implemented and measured to verify the proposed control strategy.
